Abstract

Three di¡erent life stages of spiny lobster larvae
(phyllosoma) of Panulirus homarus were fed A1-Selco-
enriched Artemia in two culture treatments, one
with the microalgae Nannochloropsis salina (green
water) and the other without the microalgae (clear
water) to assess the ability to manipulate their fatty
acid composition. Phyllosoma fed with 3-h A1-
Selco-enriched Artemia salina attained Stage VIII
(5.3mm) and StageV (3.4mm) in 42 days in the green
and clear water treatments respectively. The higher
content of the essential fatty acids in N. salina (eicosapentaenoic
acid, 25.8%; arachidonic acid, 9.5%;
and docosahexaenoic acid, 4.2%) in the green water
system increased the fatty acid content of the live
food Artemia, and ultimately the phyllosoma.
